Description

Technical Field

[0001] This invention relates to the field of bulk material conveying technology for belt conveyors, specifically a belt conveyor with a fully sealed guide trough. Background Technology

[0002] In the fields of processing, storing and transporting agricultural products such as grains, feed, oilseeds and food raw materials, belt conveyors are key equipment for achieving continuous transport of bulk materials. However, dust is generally generated during the transport of agricultural products, which not only causes material loss, pollutes the environment, and affects the health of workers, but also poses a risk of dust explosion. At the same time, agricultural products have extremely high hygiene requirements, and it is necessary to strictly prevent external impurities from contaminating the materials and to prevent the materials from getting damp and moldy, and to avoid material breakage during the transport process.

[0003] Patent application CN202323170058.4 discloses a fully sealed device for a belt conveyor guide chute, including a belt conveyor and a crossbeam: the top of the crossbeam is fixedly connected to the left and right sides, and a guide chute body is provided between the two support legs, with the guide chute body suspended above the belt conveyor.

[0004] In summary, the tension of the belt conveyor will change when transporting agricultural products to different heights and positions. If the tension is not addressed in time, there will be obvious defects in the adaptation to the working conditions. When the load is light, the tension of the belt conveyor is too high, which will aggravate the wear of the conveying system components and increase energy consumption. When the load is heavy, the tension may be insufficient, which will easily cause the conveying components to slip, ultimately having an adverse effect on the efficiency of agricultural product transportation.

[0005] To address this, we propose a belt conveyor with a fully sealed guide trough. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a belt conveyor with a fully sealed guide trough, thereby solving the problems mentioned in the background section.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a belt conveyor with a fully sealed guide trough, comprising a support mechanism, the support mechanism comprising a base, a fixed frame fixedly sleeved on the outer surface of the base, a first motor fixedly connected to the outer wall of the fixed frame on the side away from the base, and an adjustment mechanism provided at the output end of the first motor;

[0008] The adjustment mechanism includes:

[0009] The second adjustment frame has its inner wall fixedly connected to the output end of the first motor. The first motor is used to adjust the deflection angle of the second adjustment frame. A groove is provided on the outer surface of the second adjustment frame near the first motor. The inner wall of the second adjustment frame near the first motor is rotatably connected to the first drive roller via a rotating shaft.

[0010] The second telescopic rod is fixedly connected to the inner wall of the second adjustment frame away from the groove. The output end of the second telescopic rod is fixedly connected to a sliding frame. The inner wall of the sliding frame away from the second telescopic rod is rotatably connected to a second drive roller via a rotating shaft. The diameter of the first drive roller is the same as the diameter of the second drive roller.

[0011] According to the above technical solution, a third telescopic rod is fixedly connected to the inner wall of the second adjustment frame near the second telescopic rod, and a through hole is opened on the outer surface of the second adjustment frame near the third telescopic rod. There are two through holes, and the two through holes are respectively arranged on both sides of the third telescopic rod.

[0012] According to the above technical solution, the output end of the third telescopic rod is fixedly connected to a first sliding block, and the inner wall of the first sliding block away from the third telescopic rod is rotatably connected to an auxiliary roller through a rotating shaft. The diameter of the auxiliary roller is only half the diameter of the first drive roller.

[0013] According to the above technical solution, the inner walls of the two sides of the first sliding block away from the auxiliary roller are rotatably connected to rotating rods via rotating shafts, and the outer walls of the two rotating rods away from the first sliding block are rotatably connected to the second sliding block via rotating shafts.

[0014] According to the above technical solution, a conveyor belt is movably sleeved on the outer surface of the first drive roller. The side of the conveyor belt away from the first drive roller is movably sleeved on the outer surface of the second drive roller. The side of the conveyor belt away from the second drive roller is tumbling connected to an auxiliary roller. Sliding grooves are provided on both outer surfaces of the conveyor belt. A sealing material guiding mechanism is provided on the side of the conveyor belt near the third telescopic rod. By setting an adjustment mechanism, when it is necessary to adjust the conveyor belt conveying distance, the second telescopic rod pushes the sliding frame to change the length of the conveyor belt. At the same time, the third telescopic rod pushes the first sliding block to move towards the second adjustment frame. The tension of the adjusted conveyor belt is adjusted with the help of the auxiliary roller, thereby optimizing the friction between the conveyor belt and the first and second drive rollers under heavy or light load conditions.

[0015] According to the above technical solution, the outer wall of the fixed frame near the first motor is rotatably connected to the first auxiliary wheel via a rotating shaft. The first auxiliary wheel is rolled on the inner wall of the groove. The function of the first auxiliary wheel is to limit the flipping angle of the second adjustment frame.

[0016] According to the above technical solution, a hydraulic rod is fixedly connected to the inner wall of the base on the side away from the fixed frame, and a first connecting frame is fixedly connected to the output end of the hydraulic rod. A second auxiliary wheel is rotatably connected to the outer surface of the first connecting frame through a rotating shaft. During the movement of the first connecting frame, the second auxiliary wheel is used to assist the movement of the first connecting frame.

[0017] According to the above technical solution, a first telescopic rod is fixedly connected to the inner wall of the first connecting frame, and a connecting block is fixedly connected to the output end of the first telescopic rod. The inner wall of the connecting block is rotatably connected to the sliding frame through a rotating shaft. By setting a support mechanism, when the second adjusting frame deflects under the drive of the first motor, the first telescopic rod will push the connecting block to form auxiliary support for the sliding frame, thereby improving the structural stability after the conveyor belt deflects. At the same time, the hydraulic rod can adaptively push the first connecting frame to move according to the change in the length of the conveyor belt, ensuring that the whole device can be adjusted to adapt to the state of the conveyor belt.

[0018] According to the above technical solution, the sliding frame is displaced relative to the second adjusting frame by the telescopic movement of the second telescopic rod, and the second driving roller moves synchronously with the sliding frame, changing the distance between it and the first driving roller.

[0019] According to the above technical solution, the third telescopic rod linearly pushes the first sliding block and the auxiliary roller to contact the conveyor belt. The first sliding block pulls the second sliding block to slide on the inner wall of the through hole through a rotating rod. The through hole is used to limit the sliding distance of the first sliding block.

[0020] Compared with the prior art, the present invention provides a belt conveyor with a fully sealed guide trough, which relates to the technology of intelligent transportation equipment for agricultural products, and has the following beneficial effects:

[0021] 1. This invention provides a belt conveyor with a fully sealed guide trough. The second telescopic rod moves the sliding frame fixedly connected to its output end by pushing it. By changing the positional distance between the second telescopic rod and the second adjusting frame, the distance between the first and second drive rollers is adjusted synchronously, thereby achieving precise adjustment of the conveyor belt's conveying distance. During the dynamic change of the conveyor belt tension, the third telescopic rod pulls the first sliding block, causing the auxiliary roller to move synchronously, thus completing the real-time adjustment of the conveyor belt tension and ensuring that the conveyor belt is always in a suitable tension state.

[0022] 2. This invention, by setting up a sealing mechanism, ensures that the sealing and guiding mechanism can synchronously adjust its length according to the change of the conveyor belt's conveying distance, effectively isolating external factors from interfering with crops. The first sealing frame draws in special gas through the air inlet via an air pump and delivers the gas to the crop side of the conveyor belt surface through the air outlet groove, thereby further enhancing the protection effect on crops with special needs and ensuring their quality stability during the conveying process.

[0023] 3. By setting up an adjustment mechanism, the first motor drives the second adjustment frame to flexibly adjust the tilt angle of the conveyor belt during the operation of conveying agricultural products, thereby meeting the needs of conveying agricultural products to different heights. This enables the connection and conveying of agricultural products between production lines, and also completes the loading of agricultural products from low to high, adapting to the conveying operation needs in multiple scenarios.

[0024] 4. By setting up a support mechanism, during the deflection of the sliding frame, the hydraulic rod will adaptively push the first connecting frame to move according to the actual deflection height of the sliding frame and the pushing stroke of the second telescopic rod on the sliding frame, ensuring that the overall mechanism is adapted to the deflection state of the sliding frame. At the same time, the first telescopic rod applies a supporting force to the sliding frame after the deflection is completed through the connecting block, thereby ensuring the structural stability of the sliding frame after deflection and providing reliable support for the smooth operation of the conveyor belt.

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0038] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0039] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0040] Example 1: See Figures 1-6 The present invention provides a technical solution: a belt conveyor with a fully sealed guide trough, including a support mechanism 1, the support mechanism 1 including a base 101. In order to meet the needs of conveying agricultural products to different heights and positions, the device is equipped with an adjustment mechanism 5 to achieve adaptive adjustment. The first motor 103 adjusts the deflection angle of the second adjustment frame 501. By using the tilt angle formed by the second adjustment frame 501 and the base 101, the conveyor belt 2 is driven to be synchronously adjusted to the specified conveying height and position, thereby ensuring that the crops can be conveyed to the target position under different conveying needs. A fixed frame 102 is fixedly sleeved on the outer surface of the base 101. The first motor 103 is fixedly connected to the outer wall of the fixed frame 102 away from the base 101. The output end of the first motor 103 is provided with the adjustment mechanism 5.

[0041] The adjustment mechanism 5 includes a second adjustment frame 501. The inner wall of the second adjustment frame 501 is fixedly connected to the output end of the first motor 103. A groove 502 is provided on the outer surface of the second adjustment frame 501 near the first motor 103. The inner wall of the second adjustment frame 501 near the first motor 103 is rotatably connected to the first drive roller 511 via a rotating shaft.

[0042] The second telescopic rod 503 is fixedly connected to the inner wall of the second adjusting frame 501 on the side away from the groove 502. The output end of the second telescopic rod 503 is fixedly connected to the sliding frame 510. The inner wall of the sliding frame 510 on the side away from the second telescopic rod 503 is rotatably connected to the second drive roller 512 through a rotating shaft. During the process of conveying agricultural products through the conveyor belt 2, the first motor 103 provides power for the angle adjustment of the second adjusting frame 501 so as to flexibly adjust the tilt angle of the conveyor belt 2, thereby meeting the needs of conveying agricultural products to different heights. It can realize the connection and conveying between production lines and complete the feeding operation of agricultural products from low to high. When it is necessary to adjust and increase the conveyable distance of the conveyor belt 2, the sliding frame 510 fixedly connected to its output end is moved by the second telescopic rod 503. By using the change in the positional distance between the second telescopic rod 503 and the second adjusting frame 501, the distance between the first drive roller 511 and the second drive roller 512 is changed simultaneously, thereby realizing the adjustment of the conveyable distance of the conveyor belt 2.

[0043] A first auxiliary wheel 104 is rotatably connected to the outer wall of the fixed frame 102 near the first motor 103 via a rotating shaft. The first auxiliary wheel 104 rolls along the inner wall of the groove 502. A hydraulic rod 105 is fixedly connected to the inner wall of the base 101 away from the fixed frame 102. A first connecting frame 106 is fixedly connected to the output end of the hydraulic rod 105. A second auxiliary wheel 107 is rotatably connected to the outer surface of the first connecting frame 106 via a rotating shaft. A first telescopic rod 108 is fixedly connected to the inner wall of the first connecting frame 106. A connecting block 109 is fixedly connected to the output end of the first telescopic rod 108. The inner wall of the connecting block 109 is rotatably connected to the sliding frame 510 via a rotating shaft. Since the sliding frame 510 is fixedly connected to the output end of the second telescopic rod 503, when the second adjusting frame 501 deflects under the drive of the first motor 103, the first... The first auxiliary wheel 104, which is rotatably connected to the outer surface of the motor 103 via a rotating shaft, rolls on the inner wall of the groove 502. At the same time, the second telescopic rod 503, which is fixedly connected to the second adjusting frame 501, also deflects synchronously, thereby causing the sliding frame 510 to deflect with the deflection action of the second adjusting frame 501. During the deflection of the sliding frame 510, the hydraulic rod 105 pushes the first connecting frame 106 to move according to the deflection height of the sliding frame 510 and the pushing distance of the second telescopic rod 503 on the sliding frame 510. The first telescopic rod 108 supports the sliding frame 510 after deflection through the connecting block 109. Since the sliding frame 510 and the connecting block 109 are rotatably connected by a rotating shaft, the connecting block 109 only provides auxiliary support for the deflected sliding frame 510 and will not have any other additional effects on it.

[0044] Example 2: Please refer to Figures 10-11Based on Embodiment 1, the present invention provides a technical solution: When the conveyable length of the conveyor belt 2 changes, the friction between the inner wall of the conveyor belt 2 and the outer surfaces of the first drive roller 511 and the second drive roller 512 will change accordingly, which will cause fluctuations in the tension of the conveyor belt 2. Consequently, under light-load operation and transportation, the tension of the conveyor belt 2 is too high, which will aggravate the wear of the conveying system components and increase energy consumption. Under heavy-load operation and transportation, the tension may be insufficient, which will easily cause the conveying components to slip, ultimately having an adverse effect on the conveying efficiency of agricultural products. To solve this problem, this device uses a third telescopic rod 504, which, in conjunction with the auxiliary roller 507, allows for controllable adjustment of the tension of the conveyor belt 2. The third telescopic rod 504 is fixedly connected to the inner wall of the second adjusting frame 501 near the second telescopic rod 503. Two through holes 505 are provided on the outer surface of the second adjusting frame 501 near the third telescopic rod 504, respectively located on opposite sides of the third telescopic rod 504. A first sliding block 506 is fixedly connected to the output end of the third telescopic rod 504. The first sliding block 506 is located away from the third telescopic rod 504. An auxiliary roller 507 is rotatably connected to one inner wall of the retractor 504 via a rotating shaft. Rotating rods 508 are rotatably connected to the inner walls of the first sliding block 506 on both sides away from the auxiliary roller 507 via rotating shafts. A second sliding block 509 is rotatably connected to the outer wall of one end of each rotating rod 508 away from the first sliding block 506 via a rotating shaft. A conveyor belt 2 is movably sleeved on the outer surface of the first drive roller 511. The side of the conveyor belt 2 away from the first drive roller 511 is movably sleeved on the outer surface of the second drive roller 512. The side of the conveyor belt 2 away from the second drive roller 512 is tumbledly connected to the auxiliary roller 507. The two sides of the conveyor belt 2... Sliding grooves 3 are provided on the outer side of each side. A sealing guide mechanism 4 is provided on the outer side of the conveyor belt 2 near the third telescopic rod 504. The sliding frame 510 is displaced relative to the second adjusting frame 501 by the telescopic movement of the second telescopic rod 503. The second drive roller 512 moves synchronously with the sliding frame 510, changing the distance between it and the first drive roller 511. The third telescopic rod 504 pushes the first sliding block 506 and the auxiliary roller 507 to contact the conveyor belt 2 linearly. The first sliding block 506 pulls the second sliding block 509 to slide on the inner wall of the through hole 505 through the rotating rod 508. The hole 505 is used to limit the sliding distance of the first sliding block 506. During the process of the tension of the conveyor belt 2 changing, the first sliding block 506 is pulled by the third telescopic rod 504, which drives the auxiliary roller 507 to adjust the tension of the conveyor belt 2. When the third telescopic rod 504 pulls the first sliding block 506 to move towards the second adjusting frame 501, the rotating rod 508 connected to the inner wall of the first sliding block 506 through the rotating shaft will push the second sliding block 509 to slide along the inner wall of the through hole 505, thereby effectively improving the stability of the first sliding block 506 driving the auxiliary roller 507 to move.

[0045] Example 3: Please refer to Figures 7-9 Based on Embodiments 1 and 2, this invention provides a technical solution: Since the conveyor belt 2 has an adjustable conveying distance, if the fully sealed guide trough is designed with a fixed length, some areas of the conveyor belt 2 will be outside the coverage of the fully sealed guide trough during the transport of crops. This situation may cause crops with special needs to be affected by external environmental factors during transport. To solve this problem, this device is equipped with a sealing guide mechanism 4. The first sealing frame 401 is fixedly connected to the second adjusting frame 501 through the second connecting frame 402, and the second sealing frame 403 is fixedly connected to the sliding frame 510 through the third connecting frame 404. This connection method ensures that the sealing guide mechanism 4 can synchronously adjust its length according to the change in the conveying distance of the conveyor belt 2, thereby effectively reducing the impact of external factors on crops in the transport of crops with special needs. The sealing guide mechanism 4 includes... A first sealing frame 401 has a second connecting frame 402 fixedly connected to its two outer surfaces. The first sealing frame 401 is fixedly connected to a second adjusting frame 501 via the second connecting frame 402. A feed pipe 405 is fixedly connected to the outer wall of the first sealing frame 401 away from the second connecting frame 402. An air pump 412 is fixedly connected to the outer wall of the first sealing frame 401 near the feed pipe 405. An air inlet 414 is fixedly connected to the outer surface of the air pump 412. An air outlet 413 is fixedly connected to the output end of the air pump 412. When transporting crops with special needs, the first sealing frame 401 transports the crops to the transportable area of ​​the conveyor belt 2 through the feed pipe 405. At the same time, the air pump 412 draws in a special protective gas through the air inlet 414 and delivers the special gas to the crop side of the conveyor belt 2 through the air outlet 413, thereby enhancing the protective effect on crops with special needs.

[0046] A sealing cloth 407 is fixedly sleeved on the outer surface of the first sealing frame 401 away from the feed pipe 405. A second sealing frame 403 is fixedly connected to the inner wall of the end of the sealing cloth 407 away from the first sealing frame 401. The sealing cloth 407 forms a completely sealed space between the first sealing frame 401 and the second sealing frame 403. A discharge port 406 is opened on the outer surface of the second sealing frame 403 away from the sealing cloth 407. A third connecting frame 404 is fixedly connected to both outer surfaces of the second sealing frame 403. The third connecting frame 404 is located away from the second sealing frame 403. One end of the first sealing frame 401 is fixedly connected to the sliding frame 510. An elastic cloth 408 is fixedly connected to the inner wall of the second sealing frame 403. The elastic cloth 408 expands and contracts elastically as the distance between the first sealing frame 401 and the second sealing frame 403 changes, thus preventing crops from splashing everywhere. The end of the elastic cloth 408 away from the second sealing frame 403 is fixedly connected to the inner wall of the first sealing frame 401. Second motors 409 are fixedly connected to both sides of the inner walls of the first sealing frame 401 and the second sealing frame 403, respectively. The output ends of the second motors 409 are all fixedly connected to a first adjustment mechanism. The first adjusting frame 410 has a third auxiliary wheel 411 rotatably connected to its outer wall on the side away from the second motor 409 via a rotating shaft. The third auxiliary wheel 411 rolls along the inner wall of the sliding groove 3. When the conveyor belt 2 inside the sealed material guiding mechanism 4 conveys crops, the raised edges on both sides of the conveyor belt 2 form a natural barrier, effectively reducing the risk of materials slipping to the sides during conveying. At the same time, the second motor 409 drives the third auxiliary wheel 411 through the first adjusting frame 410, causing it to roll along the inner wall of the sliding groove 3 opened on the outer surface of the conveyor belt 2. This structure can support the raised edges on both sides of the conveyor belt 2, thereby effectively preventing the conveyor belt 2 from deviating due to shaking and vibration during the conveying process, helping it to maintain the central conveying position and reducing deviation. In addition, when conveying small-particle crops, the second motor 409 can adjust the raised angle of both sides of the conveyor belt 2 through the third auxiliary wheel 411, so that the conveyor belt 2 forms a trough structure. The trough structure can naturally gather the crops in the central area of ​​the conveyor belt 2, preventing the material from being dispersed to both sides, thereby achieving more stable and efficient conveying of granular crops.
